Travelocity.com and currency-exchange company Travelex have agreed to operate an area on Travelocity's site where customers can exchange 80 different currencies online. The My Travel Wallet service will also allow travelers to purchase international traveler's checks or prepaid global cash cards and have them delivered as quickly as overnight. In an effort to one-up the competition, online travel agencies, such as Travelocity, Orbitz and Expedia, have steadily added new services and shopping tools during the past year. --Greg Sandoval, Special to ZDNet News
